As a professor of neurosurgery, oncology, plastic surgery and pediatrics at the Johns Hopkins School of Medicine, Dr. Benjamin Carson directed pediatric neurosurgery at the Johns Hopkins Children’s Center for more than a quarter of a century. In 1987, he completed the first and only successful separation of Siamese twins conjoined at the back of the head, an accomplishment documented in the award-winning movie “Gifted Hands: The Ben Carson Story.” In 2008, he was awarded the Presidential Medal of Freedom by the president, which is the highest civilian honor. In addition, Carson is president and co-founder of the Carson Scholars Fund and has written five best-selling books, including “America the Beautiful: Rediscovering What Makes this Nation Great,” which was No. 1 on the New York Times best-sellers list in March 2013. In June, 2013, after 40 years of medical endeavors, Carson retired and today serves as Professor Emeritus of Neurosurgery at Johns Hopkins University.
